Patented July 20, 1909.

Application filed March 20, 1908. Serial No. e22,292.

T all whom it may concern:

Be it known that I, HA ViN I-lEns'rnoM, of

the city of Winnipeg, in the Province of Mani toba, Canada, mechanic, have invented certain new'and useful Improvements in Conibi nation Side and Grain-Car Doors, of which the following is the specification.

My invention relates to combination side and grain car doors.

A still further object is to provide a door which will allow no leakage of grain and which whennot in use is entirely out of the way.

, 1t consists essentially in a deer formed in two sections the upper section of which is hinged frem theupper cross beam and the lower sectienof which is carried by a set of hangers operating on a track, means carried by the lower section of the deer whoreby'it may be raised and lowered in respect to the hangers, means carried by one of the door posts to receive one edge of the lower door section, and means, carried by the other of said door posts, adapted to close ever the lower section when in position, the parts be ing arranged and constructed in detail as hereinafter more particularly described.

Figure 1 is a side view of a car supplied with my door, the door being shown in an open position. Fig. 2 is a vertical sectional view through the car, the section being taken in the plane denoted by the line X X, Fig. 1,

and looking in the direction of the arrow.-

Fig. 3 is a vertical sectional view through the door and car frame, the section being taken in the plane denoted by the line Y Y in Fig; 4f, the door being closed. tal sectional view through the lower section olthe door and the door post,'the section being taken in the plane denoted by the line Z Z, Fig. 3. Fig. 5 is an enlarged detailed perspective view showing the manner in which the sections of the door are locked to gether. Fig. 6 is a perspective view of a por- I tien of one side of the door.

In the drawings like characters of reference indicate correspondlng parts 111 each figure.

Fig. 4 is a horizon- 1 represents the sill, 2 and 3 the door posts, andd the upper cross beam of an ordinary ear, of which 5 is the usual doorway opening.

Gropresents the roof of the car and 7 are the side or face boards.

The door is composed of two sections of which 8 represents the upper and 9 the lower,

such sections being adapted to completely fill the doorway opening, when closed, the one 8 being hinged to the cross beam 4. The lower section 9 has ahorizental red 10 carried centrally thereon, the rod being secured to the outside of the door section by straps 11 and 1.2 respectively. The ends of the red are each formed with a crank 13 and 14 respec-v tively, the crank ends being beyond the straps, and at the center there is a side eXtension or lever 15, for a purpose later described. The lever has an opening 16 therein which is adapted to close over an eye 17 fastened on the door.

18'is a track on the outside of the'car at the top and passing longitudinally'o'l' the car. The ends of thetrack are enlarged at 1.9 and bolted or otherwise fasten d to the lace boards 7.

20 is a bracket secured to the door post 3 and it passes outwardlyto thetrack substan tially midway oi itslength. I a I l 21 and 22 are rollers or wheels o mrating on the track and carried at the upper end of the hangers 23 and 24 which pass downwardly to the crank ends 13 and let and have their lower ends fastened thereto.

25 and 26 are a second set of straps l'astened to the lower section of the doerand passing outwardly and around the hangers, it being noticed that they allow of an outward and inward movement of the hangers,

27 is an angle iron fastened to the straps 23 and 24; at the top, spacing tlrem, such angle iron havingthe horizontal arm passing directly under the track thereby preventing the rollers or wheels from leaving the track.

28 and 2 9 are rests or brackets fastened to the face boards of the car and are adapted to receive the lower edge 01' the under section of the'deor when it is open. This position is shown in Fig. 1.

I Theinner corner of the door post 2 is cut away at 2 to form a channel, the channel being practically the same width as the thickness of the deer, and of a length equal to the height of the lower section 9.

30 is an iron plate fastened to the inner edge of the deer and completing the channel.

To all whom it may concern:

Be it known that I, HERBERT. S. HUM- BHREY, a citizen "of the United States, residing at the city of Kalamazoo, county of Kalamazoo, and State of Michigan, have in vented certain new and useful Im rovements in Water-Heaters, of which the to lowing is a drawn, or when the drawing of the water ceases, is effectively prevented. Third, to provide an improved Water heater in which the water is'maintained at a substantially even temperature, so that hot water may be drawn at any time, and'one which is of large capacity, and at the same time is comparativel economical of fuel in'maintainin the supp y ofhot water; Fourth, to provi e an improved valve mechanism, whichis very simple and economical in structure, and one which is not likely to get out of repair in use. Further objects, and objects relatin to structural details, will definitely appear rom the detailed description .to follow.

1 accomplish the objects of my invention by the devices and means described in the followin specification. The invention is clearly efined and pointed out in theclaims. A structure embodying the features of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

the en' s of the sectionlinesm...

Referring to the drawing, the heater 1 is preferably of the coil type,.and I have illustrated such a structure in this, a plication.

Fig. 5 is an enlarged This heater is provided with a p urality of heating coils, as 2 and 3, four coils being rovided in the structure illustrated. T ese coils' are substantially continuous from top to bottom, a circulation connection being provided for a part of the heater, the bottom coilbeing the circulapion coil in thestructure illustrated, aswill be described later. These coils are arranged within the heater casing, which is referably provided with a double wall as il ustrated,-to revent radia-" tion. The gas burners 4 are ocatedbelow thecoils. The supply or inlet wateris'de livered to the upper end of the coils, through the, inlet valve casing 5, which is provided --with a cold water inlet 6, and a cold water discharge 7, the inlet 6 being connected with the water supply, and thedischarge 7 being connected to the inlet pipe 8, at the upper end of the heater coils. he. valve casing is preferabl also rovided with a'hot water inlet '9, an a disc argelO, the hot water inlet 9' being connected to the delivery pipe 11 of the heater preferably through the thermostat tube 12. The hot water inlet is preferably connected to the cold water discharge by means of they circulation port 13, so that,

' when this port 13 is open, the water may pass into the discharge 7, and, under certain con- 'ditions, which will be later pointed out circulate through all the water coils and the thermostat. The water discharge 10 is connected to the house system or to a draw-off faucet, as 13 through the pipe 14, the faucet being here illustrated for convenience. The hotwater discharge is controlled by a regulating' valve 15, w ich regulates the amount of the water which may pass through the heater. This valve is here illustrated closed,

butit will be understood that in the operation of the heater it is always open more or.

so the nomical of fuel!" less to regulate the amount of water which can pass through the heater during a given time. The waterinlet valve 16 is preferably of the iston type and is adapted to be automatica yopened by the pressure of the inlet water when the draw-01f faucet is open, thereby reducing the pressure within the heater or system, or causing a variation in the pressure in the water supply and'in the heater. The valve casing is a so rovided with a circulation passa e 17, whic is connected as through the pipe 18, tothe upper end of the bottom coil 4.

For convenience in manufacture the up or end of the bottom coil and the lower end of the coil next above are provided withextensions 19, which project through the wall of' the heater, and are connected with ,a coupling member 20, with which the circulation pipe 18 is also connected. This arrangement, however, is l'ar ely one of convenience.

When the water is emg drawn from the heater, itpasses from the top down through the coils to the discharge ipe 11, thence through the thermostat, to t e discharge 10,

of the valve casing. When. the water is not bein drawn, the water circulates throu h ottom coil, and the thermostat. T e advantage of this is that a supply of hot wateris at hand for practically mstantaneous' use in opening the faucet, and at the same time but little volume is required to be kept heated when the water is not being drawn off, thereby making the structure very eco The circulation passage 13 is controlled by circulation valve 21, which is mounted upon the stem 22 of the water inlet valve 16. This circulation valve 21 is preferably loosely mounted upon the valve stem, and is yieldingly held against the rest 23 by means of the spring 24. v This sprin' 24 is preferably a coiled spring arranged a out the stem, its u per end bearingyagainst the valve 16, and 1ts lower end engaging the circulation valve 21. The rest" 23 is preferably made adjustable, so that the valve 21 seats at the desired point prior to the opening of the inlet valve 15. The further advantage of this adjustment is thatit obviates the necessity of great care in manufacturing and fitting the parts. On the section 2510f the inlet valve stem 22 I arrange a return spring26. This spring 26 is compressed by the opening of the .valve 16 and expands to return it to its seat. The springlis preferably arranged in a chamber 27, W 'ch is of the form of a cylindrical cap-{like extension to the valvecasing, and w 'ch cap can be removed with out removing the mam cap of'the valve casing. This ermits the adjustment or the renewal of t e sIpring26, without disturbing the packing of t e main cap. This structure and arrangement of the inlet valve and the the valve is a coiled spring 31.- The valve stem is provided with a stop 32, to limit the movement of the piston member thereon. The valve 28 is held normally open by means of'the sprin 33, arranged on the valve stem, the s ring ei preferably in the cap-like meml er 34. The valve actuating member 30 being arranged in.the discharge for the supply, water is actuated when. the inlet va ve is open, thereby closing the circulation valve. This compels the water passing through the heater to circulate down and outthrough the discharge pi e 11, instead of circulating or passing upt rough the circulation pipe 18v to dlscharge. When, however, water is not being drawn from the heater, it circulates ashas been described, through-the lower part of the heater, or a art only of the heater, and the thermostat. n the event that the circulation valve should fail to open, after the water inlet valve is closed, the circulation will then be ast the valve 21, to the upper end of the eater. suddenly closed, the current of water will pass through the circulation valve 21 and past the valve actuating member 30, until the shock is relieir'ed, thereby, in a measure, preventing Also-when the draw-off faucetis also to the thermostat, so that the water' inlet valve and the thermostat coact tocontrol the same.- The gas-is, by this arrangement, automaticall. turned on'b the draw-' ing of water from t e heater, an held or re tamed on by the thermostat until the water reaches a predetermined heat after the drawstem 41 and the water inlet valve stem 22 with a link connection, the links being arranged in'the form of a toggle. A pair of links, as 42 are pivoted to the valve ste1n,'as by means of the pivot 43, and pivotally connected as by means of the pivot 44. Carried by these links is a rest 45 for the thermostat lever 46. This lever 46 is mounted on a pivot 47 on the gas valve casing, and is acted upon by the lever 48, which is mounted upon a pivot 49 on the water valve casing. This lever 48 is operatively connected'to the thermostat member 50. This thermostat member is arranged 'i'nthe tubular thermostat member 51, which extends into the thermostat tube 12: The rest 45 is preferably provided with downwardly projecting guiding stem 52, which engages the guiding slot 53, in the connecting yoke 54 for the Water and gas valve casing in Figs. 3 and 6. In the structure illustrated the thermostat member 51 is the member possessing the greatest degree of expansibility, so that, as the same is expanded by the water becoming heated, the pressure on the thermostat levers is released, allowing the gas valve to close, a spring, as 55, being preferably provided for this purpose. The stem 41 is preferably slidably connected to the valve 40 to relieve the parts of strain, and this avoids the necessity of accurate adjustment.

The rest 45 is preferably held yieldingly upward, by means of the coiled spring 56 arranged on the guiding stem forthe rest. When the; temperature falls below the predetermined point, the thermostat, acting through the connection described, opens the gas valve. In the use of the heater the outlet is open, and the incoming water opens the inlet valve and, through the connections described, the gas valve, so that, both the water inlet valve and the thermostat coact in controlling the gas valve, This inlet valve is, so far as the operation of the gas valve is concerned, merely a water-actuated member,

and its form and operation might be very greatly varied and the same results be ac' complished. I, however, prefer to use the water inlet valve for the purpose, as is illustrated. "While this arrangement for con trolling the gas is desirable for use in connection with the circulation features mentioned and described, it is obvious that they might be used in other relations to advantage.

The burners are provided with a suitable pilot 57 which is connected by the pi e 58 to the valve casing. The regulating va ve 15 is located in the discharge passa e so that it is beyondthe thermostat. By the adjusting of this valve the temperature of the water can be controlled, as it is obvious that it regulates the amount of water which will pass through the heater in a given time when the draw-oil faucet is open.

A blow-off cock as 59 is provided, and this is preferably located at the lower end of the thermostat tube 12, and in the structure illustrated, in the coupling member 60 for the thermostat tube, to the discharge pipe 11 of the heater. When located in this position, it is obvious that by opening the same, water is forced through all the coils of the heater, thus carrying out any sediment which may have collected therein, and the sediment which might collect in the thermostat settles to the bottom of the tube 12, so that it is also carried out.

By thus arranging the parts, I secure an automatic control for the heater and the temperature of the water drawn off is capable of quite accurate regulation, and the overheating of the water or heater is prevented.

Further, the apparatus is, as described, economical to operate, in that normally the water acting upon the thermostat when the water is not beingdrawn, circulates through a small portion only of the heater, and this water being at the discharge end of the heater, is in )osition to be drawn oii first, when the outlet is opened, thereby securing a prompt su ply of hot water.

I have il ustrated and described my improved water heater in detail in the form preferred by me on account of its structural simplicity and economy and the convenience with which the several parts may be assembled. I am'aware, however, that my invention is capable of very great variation in structural details, without departing from my invention, and I desire to be understood as claiming the same broadly, as well as specifically.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
